object is not an instance of declaring class
Hi,
I am developing a client with dynamic loading.
So far, when I do the invocation, it works properly.
However, if I invoke the same service several time within short period (let
say , 10 seconds),
I might get exception of "object is not an instance of declaring class".
If I trace the message being sent in/out, both are correct. Seems like
the client could not serialize/deserialize it in a short period.
Has anyone encountered this kind of problem?
Appreciate if someone can explain what caused this exception.
Thanks...
Herbert
